Implementations and examples of fiber lasers based on fiber laser cavity designs that produce self-similar pulses ('similaritons') to achieve a pulse spectral bandwidth greater than a gain spectral bandwidth based on a spectral broadening fiber segment and a spectral filter to ensure the proper similariton conditions.

Broadband short pulse fiber lasers capable of generating output spectra broader than gain bandwidth

A normal-dispersion fiber laser is operated using parameters in which dissipative solitons exist with remarkably large pulse duration and chirp, along with large pulse energy. A low-repetition-rate oscillator that generates pulses with large and linear chirp can thus replace the standard oscillator, stretcher, pulse-picker and preamplifier in a chirped-pulse fiber amplifier.

Giant-chirp oscillator for use in fiber pulse amplification system

Implementations and examples of mode-locked fiber lasers based on fiber laser cavity designs that produce self-similar pulses ('similaritons') with parabolic pulse profiles with respect to time at the output of the fiber gain media to effectuate the desired mode locking operation. An intra-cavity narrowband optical spectral filter is included in such fiber lasers to ensure the proper similariton conditions.
